1. To understand the anatomy and variations of papillary muscles 2. To discuss the role of MRI in the evaluation of papillary muscle abnormalities 3. To illustrate the several abnormalities that is seen in papillary muscles. 4. To understand the significance of papillary muscle anatomy in hypetrophic cardiomyopathy, LV partitioning device placement, etc.   

• Papillary muscle anatomy- vascular supply • Anatomical variants of papillary muscle- Accessory muscles • Role of CT/MRI in evaluation (Cine imaging, delayed enhancement, tagging, perfusion) • Description and illustration of the following abnormalities                  Parachute mitral valve, parachute like asymmetric mitral valve                  Shone complex                  Hypertrophic cardiomyopathy                  LVOT obstruction by papillary muscle                  Anomalous insertion, apical displacement, Hypermobile muscle                  Papillary muscle dysfunction                  Infarction                  Rupture                  Mitral incompetence due to papillary abnormalities                  Calcification                  Benign Neoplastic masses- Fibroelastoma, myxoma, rhabdomyoma                  Malignant neoplastic masses- Metastases, sarcoma, lymphoma                  Non neoplastic masses- Thrombus                  Accessory muscle mimicking thrombus                  Anatomy for LV partitioning device.
